Narrative:
Flight segment was fat to ont. IMC en route, first officer was having trouble holding altitude and course. No turbulence, light rime icing. I had to continually remind first officer to maintain altitude or course. First officer has 'repeaters' for instruments and they take a while to get used to. Everyone manages though. It was mentally draining having to act as flight instructor for 40 mins and when we went VMC I became very relaxed. That is how the problem arose. At that point I was so drained that I failed to monitor the progress of the flight. We passed hitop by 7 mi and were reprimanded by socal approach. Then we deviated from altitude, 400 ft low, in the resulting confusion. All in VMC. As it turns out the first officer only had 26 hours of instrument time, and no time as a flight instructor. That is a severe disadvantage in a commuter environment. Myself, I am a new captain and have my hands full anyway just getting procedures honed, etc. These deviations occurred as a result of my failure to monitor the progress of the flight. Contributing factors were: pairing up a new first officer with a new captain. Pairing up a weak first officer with a new captain. To keep this from occurring again, I will be more vigilant during all phases of flight VMC or IMC, and work with the first officer to get her up to speed on instruments.

Title: THE FLC FAILED TO TURN AT THE REQUIRED TURNING POINT. THE FLC DEVIATED 400 FT OFF ASSIGNED ALT.
Narrative: FLT SEGMENT WAS FAT TO ONT. IMC ENRTE, FO WAS HAVING TROUBLE HOLDING ALT AND COURSE. NO TURB, LIGHT RIME ICING. I HAD TO CONTINUALLY REMIND FO TO MAINTAIN ALT OR COURSE. FO HAS 'REPEATERS' FOR INSTS AND THEY TAKE A WHILE TO GET USED TO. EVERYONE MANAGES THOUGH. IT WAS MENTALLY DRAINING HAVING TO ACT AS FLT INSTRUCTOR FOR 40 MINS AND WHEN WE WENT VMC I BECAME VERY RELAXED. THAT IS HOW THE PROB AROSE. AT THAT POINT I WAS SO DRAINED THAT I FAILED TO MONITOR THE PROGRESS OF THE FLT. WE PASSED HITOP BY 7 MI AND WERE REPRIMANDED BY SOCAL APCH. THEN WE DEVIATED FROM ALT, 400 FT LOW, IN THE RESULTING CONFUSION. ALL IN VMC. AS IT TURNS OUT THE FO ONLY HAD 26 HRS OF INST TIME, AND NO TIME AS A FLT INSTRUCTOR. THAT IS A SEVERE DISADVANTAGE IN A COMMUTER ENVIRONMENT. MYSELF, I AM A NEW CAPT AND HAVE MY HANDS FULL ANYWAY JUST GETTING PROCS HONED, ETC. THESE DEVS OCCURRED AS A RESULT OF MY FAILURE TO MONITOR THE PROGRESS OF THE FLT. CONTRIBUTING FACTORS WERE: PAIRING UP A NEW FO WITH A NEW CAPT. PAIRING UP A WEAK FO WITH A NEW CAPT. TO KEEP THIS FROM OCCURRING AGAIN, I WILL BE MORE VIGILANT DURING ALL PHASES OF FLT VMC OR IMC, AND WORK WITH THE FO TO GET HER UP TO SPD ON INSTS.
